Subject: Re: [ubl] Namespace versioning
I agree that it would be nice if the Schema version could be identified separately to the namespace version, but the optionality of the W3C XML Schema 'schemaLocation' attribute doesn't lend itself to robust identification. More importantly, what are we doing to do about organisations that won't accept XML instances with a 'schemaLocation' due to the security implications (i.e. that the 'schemaLocation' can point to arbitrary URL with unknown results when something is downloaded from that URL). Cheers, Tony.
